Question

In right triangle ABC, if A=15 degrees, c=37 and angle c is the right angle. Solve the triangle. Round to the nearest tenth, if necessaary.

Answer 1

well to get angle B
know that there are a total of 180 degrees in a triangle
angle C = 90 (definition of right angle)
angle A = 15
so angle B = 180 - 90 - 15 =

Answer 2

i got 75

Answer 3

but what about the 37

Answer 4

yep :)
so the over all problem looks like

Answer 5

then you can use cos to find side b
cos(15) = sideb/37
so sideb = cos(15) times 37 =

Answer 6

and you can find side a by
sin(15) = side a / 37
so side a = sin(15) times 37 =

Answer 7

9.576304668811

Answer 8

yup a = "9.576304668811"
then b = 37(cos(15)) =
